3578-3580 18th St, San Francisco, CA 94110

The three-story multi-family residential building at 3578-3580 18th Street, owned by Eduardo L. Castillo and Josefa, is a 6-unit apartment complex constructed in 1905 in the Mission Dolores neighborhood. The property has undergone several significant improvements over the years, with the most notable renovations occurring in 2004-2005 when comprehensive window replacements took place, including the installation of 29 replacement windows and repairs to dryrot issues, with costs totaling over $60,000.

The building's maintenance history shows attention to basic infrastructure, including reroofing in 2005 and occasional street space permit usage. Recent inspections and complaints reveal ongoing maintenance challenges, with the most recent concern filed in May 2024 regarding inadequate ventilation and chimney issues affecting resident comfort. Prior issues have included mold problems (2015), an incident involving a disabled toilet seat (2012), and various maintenance concerns in 2001, including ceiling plaster issues and ventilation problems.

The building appears to have addressed many historical violations by March 2001, including fire safety concerns and interior surface problems, though some issues persist into recent years. The surrounding area has experienced recurring issues with abandoned mattresses and debris, as documented in multiple 311 calls throughout 2024-2025, and there have been some concerns about graffiti on nearby infrastructure. The property has maintained compliance with most building requirements since the early 2000s, with no active violations currently on record, though the recent ventilation complaint suggests ongoing maintenance needs.
